Fig. 34 is a view of blank mold interior spray device and the controltherefor.

The machine is shown as a readily portable installation. It has mainplatform 1 mounted on grollers 2. Columns 3, 4, rise from the platform.1.

The drive and control ,as Electric power line conduit 5 extends toswitch 6 on the platform 1. Throwing in this switch 6 effects startingof electric motor 7 having shaft 8 carrying pulley 9 from'which extendsbelt 10 vabout pulley 11 on shaft 12 mounted in bearings 13, 14, rising'from the platform 1 on which the motor '7 is also mounted.v On thisshaft 12 is nut 15, adjustable to vary the compression of helical spring16 for holding splined clutch collar 17 into transmission engagementwith clutch member 18 on shaft 19 aligned with the shaft 12 and mountedin bearings 20, 21, rising from the platform 1. This shaft 19 hasthereon worm 22 in mesh with worm wheel 23 lose on shaft 24 rising fromthe platform 1. Housing 25 is about this worm wheel 23 and gear 26 isxed with the gear 23. This gear 26V is in mesh with gear 27 on thecolumn 3 determining the driving rotation'of the blank mold carrier.'I'his rst carrier gear 27 is directly in mesh with gear 28 on thecolumn 4 as the drive for the blow table or second car.- rier insynchronism with the first carrier. In practice hereunder, it iscontemplated thel rota.- tion shall be continuous. For bringing thecan'iers to a desired angular position, manually, it is only necessaryto operate hand Wheel 29.

Opening ofv valve 3 0 permits supply of power air to line 31. Emergencyvalves 32vat various positions about the machine may be thrown to cut inair to power cylinder 33, thereby through lever 34 shiftingclutch collar17 away Ifrom its companion clutch member 18 against the spring 16. Themotor 7 is thus rendered ineffective for driving the worm 22. Resettingof the thrown emergency valve 32 to running position effects exhaustingof the cylinder 83 through such valve allowing the spring 16 to forcethe collar 17 into engagement with the clutch member or collar 18 andthe machine to again enter upon regular running operation.

In tank 35 is molten glass supply or pool 36. From this tank 35 thereprotrudes laterally, overhang 37 having exposed area 38 into which molrrer.)

ten glass 39 may flow up to the level of the pool 36, by way of opening40 under'arch 41 (Fig. 2); Approximating the underside of the arch 41above the level of thepool 36, there is refractory metal shield 42resting on the overhang and extending to the arch 41, with an opening 43in such shield which restricts the area exposed, reducing theatmospheric cooling of the molten glass in the pool 36. Herein thisopening 43 is shown of arc form for suction gather of molten glassupward through open bottom 44 into blank mold 45, 46, during thecontinued movement of the blank mold.

` The blank mold carrier The blank carrier gear 27- (Fig. 8) is xedwithy spider 47 upwardly therefrom about the column 3 applied on plungerhead 57 effects thrusting of the neck finish mold sections 5`3, 54 apartor into open position against the resistance of tension helical spring58 (Fig. 21) therebetween.

The nipple box The arm 50 forwardly of the minor mold section openingplunger head 57 has housing 59 (Figs. 8, 15, 19). Ears '60 from saidhousing 59 have bearings 60 which mount upwardly extending lever 61terminating in roller 62 at its free end. This lever 61 mounts pin' 63which has pivot pin connection 64 with link 65 having slots 66 with-which coacts'pin 63 carried by the ears 60. This link 65 has link67^therefrom to piston 68'recipro'- cable in the housing 59 by rockingof the lever 61.

At the position of the parts in Fig. 8. suction in chamber 69 of the arm501s in communication by ducts 69 with chamber 70 from which extendducts 71 through member 72. These ducts 71 `extend into the blank moldsections for there developing the suction gather. At the position inFig. 19, the suction gather has occurred. Liftingof the piston 68 hasraised plunger 73 and carried sleeve 74 upward therewith for connectingpressure'air supply chamber 75, by way of ports 76, 77, 78, with chamber79 about the plunger 73 for entrance of blank blowing pressure air .8)to have their open bottom 44 approximate a horiof the plunger 73 in thering 83 is due to action of spring 84. The inclusion of this neck ringmold section 83 is of more value for adoption in connection withso-called wide-mouth ware and milk bottles to form ledges and aiding toprevent blowing away of such ledges and for an additional chilling for apredetermined section of the neck or finish.

The further adjustable rocking of the lever 61 after lifting the ring83, may depress the wedge 55 for opening the neck flnishmold sections53,

54, in nally releasing the blank or parison in effecting a transfer.

' The gather Fixed with the arm 50 as an angle lever is depending arm 85carry-ing fixed therewith shaft 85 terminating in roller 86 havingassembly means 87 for eccentric sleeve 88 locked in its angular positionas to the arm 85 by set screw 89 (Fig. For holding the blank `-moldsections as closed zontal plane, the roller 86 rides along xed cam 90(Fig. 5). This cam 90 is mounted on the column 3.

In the rotation of the carrier 27, 47, the roller 86 rides from theconcentric cam 90 to cam 91 outward to lift holding cam portion 92,effective to tilt the arm 50 to such extent that the blank mold sections45, 46are clear of the shield 42v at the overhang 47. Further travel ofthe roller 86 into dip portion of cam 93; lowers the open bottom 44 intothe opening 43 of the shield 42 to approximate the upper surface 39 ofthe molten glass.

Air suction line 94 (Figs. 16, 17, 18) has connection 95' with block 96.Nicety in angular adjustment may be had to vary application of vacu- .umto charge the blank in a restricted exposed area of the pool 36. Thisadjustment is effected yby shift-ing the block 96, which isbrought aboutby rotation of threaded stems 97, 98. This block 96 rests on plate 99having ports 100 therein for the respective blank mold carrying rockers50, 85.

Each port 100 is in communication with a chamber 101 having thereincheck valve 102 (Fig. 8) openable by reduced pressure in such chamber101. Housing 103 for this chamber 101, has a rigid tubular extension 104of arc or gooseneck form extending through gland 105 for communicationwith the chamber 69. The arc of this duct or pipe 104 is kon a radiusfrom the fulcrum bearing 49. It isy thus seen that angle lever 50, 85,may rock relativelyv to the spider 47 and that therl is still preservedair connection therebetween at the gland 105 through which the pipe 104may reciprocate, while the air connection to the rotary chamber 101 isfrom the block 98 having timed communication through a port 100. For abrief angular travel the suction is thus effective, timed4 to occur atthe touching or approximate touching of the glass surface 39 by the openbottom 44 of the blank mold.

The roller 86 rides'out of this dip portion 93 upon cam portions 105,106, back to concentric portion 90, in lifting the blank from itshorizontalbottom gathering position for tilting over the forebay andthen settling back to its normal travel region to approximateperpendicular or vertical position for the closed blank mold.

The shear Loose upon the depending arm is sleeve 107 (Fig. 8) from whichrises fulcrum bearing providing bracket 108. From this fulcrum bearingarm 109 extends upwardly and outwardly. Set screws 110 (Figs. 13, 14)may be slacked as to one thereof and run up as to the other to effectdesired tilting of ilat stem 111 terminally carrying plate 112 to havesuch plate a desired rake or angle for approach to the opening 44 of theblank mold. This plate 112 is provided with V-shaped notches 113 toserve as severing means or a shear, and is reversible for differentassembly so that one notch may be used after the other has become wornto an undesirable extent. This plate 112 is provided With notches 112',one of which seats at fixed pin 111' where it is held by opposing gib112 at the beveled longitudinal side of the plate 112. Screws 111"anchor the gib detachably to permit the reversal of the plate 112.

This shear arm 109 as carrying the blank mold combined shear and baiileplate or bottomclosure, is not directly mounted on the fulcrum bearingbracket 108, but has dove-tail seat 114 as a slide connection withdepending arm 115 which has direct mounting on pivot` bearing 116 in thebracket 108 (Fig. 8). This depending arm 115 terminates in roller 117.This arm in the region of the slide is provided with ear 118 for screw119 extending to ear 120 fixed with the arm 109, thereby adjustingnicely the horizontal plane for the plate 112 up and down as to the arm115. Clamp 120 locks arm 109 in adjusted position.

The shaft 85 has iixed therewith cam 121, 122 (Fig. 12), with which theroller 117 may coact. The portion 121 serves to hold the baille 112 inclosure position. From the sleeve 107 there extends 'bracket 123downward past the roller 86y to arm 124 pivoted on the shaft 85' andvcarrying roller 125 which as riding on concentric cam 126 has eifectedsuch angular shifting of the sleeve 107 that the baffle or closure plate112 is away from the blank mold bottom opening 44.

In the closed circuit cycle of travel of the blank mold, the roller 125,rides along the cam 126 (Fig. 5) and cam portions 127, 128 into cam 129for swinging the closure 112 under the blank mold as such rises from theglass pool-with a gather sucked thereinto. This shearing operation iseffected at the cam portion 130 with cam 131 therefrom holding the plate112 as a closure during blank blowing.

The blank blowing may continue along cam portion 132, while cam 133(Figs. 5, 6) mounted in guide 134, may be angularly shifted by handle135 and locked by set screw 136, in thereby adjusting the time forswinging of the closure 112 away from the bottom 44 of the gather in theblank mold.

Gather cut out Rotary stem 137 (Figs. 5, '7) operable on threaded stem138 may shift block 139 to cause the cam 93 to rock on its bearings 140in bringing arc face 141 outward more or less to approximate the rangeof cam portions 92, 105. There is thus provided cam continuity forvarythe pool or-for other control purposes in machineV operation,effective during the running of the machine.v

As a safety device against stopping the machine with a blank mold in thepool, when an emergency stop is made, line 142 extends to cylinder 143(Figs. 4, 7) for moving the cam face 141 outward into dip eliminatingposition by the action of piston rod 144, where it is held by the powerair until the emergency condition is removed. Upon starting of themachine, the load of the roller 86 will reset the carn 93 as thenpermitted by the cylinder 143 which has been exhausted. The power airsupply line 31 has branch to valve 31 opened when there is suchresistance to machine driving that the clutch pins of the clutch member18 thrust the collar 17 by sliding past the sockets therein. Thisautomatic unclutching, not s only stops the carrier rotations for themachine,

but swings the arm 34 to open the valve- 31'. Power air is thus suppliedto line 32' independently of by way of the valve 32. The cylinder 33thus acts to hold the` machine drive disconnected. This power air alsoflows past check valve 32 and by way of the line 142 to rock the camface 141 into position to` hold the gather mold sections 45, 46, clearof contacting the pool of glass.l

Blank blowing Cam 145 coacts with the roller 62 after the transfer forrocking the lever 61 outward or upward for bringing the plunger 73 intofully depressed position, which position it retains until past thegather station, when the roller 62 rides into cam 146 (Fig.'l) forlifting the plunger 73 in bringing the nipple box elements into theposi- -tion in Fig. 8. Adjusting device 147 is provided for effectingangular shifting of this cam 146 for timing the initial openingformer orplunger 73 for regulating the chilling of the neck and lip.

Pressure air lines 148 extend to valves 149 in block 150 (Fig. 16)riding on the ring plate 99. The valves 149 determine the effective arcfor blowing of air through the port 99 into the chamber 101 from whichiiexible ducts 151 (Fig. 8) extend to the chamber 70.

During the blowing operation for the blank, the plunger 73 ismaintained'y withdrawn from the blank 81..y Cam elements 152 areassembled for the desired arc interval, and removed as it is desired toshorten such interval, with placing of cam portion 153 terminally (Fig.1). Upon passing the cam portion 153, the roller 62 is operated to suchextent that the ring 83 is lifted clear of the blank lip 80.

Blank mold opening From the blank mold sections 45, 46 (Fig. 16), extendadjustable links 154 to arms 155 of angle levers having fulcrum bearingpins 156.' Fixed with the arm 155 is arm 157 having yieldable link 158extending to arm 159 having fulcrum bearing 160. Fixed with the arm 159is arm 161 having roller 162 (Fig'. 8). This roller 162 as riding intocam portions 163,164 (Fig. 1), eiects opening of the 'blank mold bymoving the sections 45, 46, away from each other, thereby leaving theblank suspended from the neck finish mold sections 53, 54. 4

This opening of the major blank mold sections has released the neckiinish mold sections, for

adjustable compression linkage devices 166 (Figs.

16, 23) have rocked angle levers 167 to have adjustable stops 168 clearof the sections 53, 54.

Blank heating There is utility for superior ware forming, and

even for removing shear mark in the formed blankl -by exposing such assuspended to a reheating operation. To this end valve 169 in gas linev170 extends to fitting 170. Air line valveV 171 in air line 172controls air supply to this fitting which extends upwardly to flareburner device 173 (Figs. 10, 11) at box 174 having upper notch-way 175thereacross as a passage for the lower portion or body 81 of thesuspended blank. This burner device m'ay be accurately controlled forthis heating blast to melt out any shear mark or deformation at theclosure region.

Transfer The suspended blank 81 as passing the burner 173, is held onlyby the major or neck finish blank mold sections 53, 54. The roller 62 asapproaching the region of meshing between the gears 27, 28 of therespective carriers, rides into cam portion 176 (Figs. 1, 20) whicheffects sufiicient depressing of the wedge 55 (Fig. 8) to provide aloo-seness to establish a minute movement apart of the sections 53, 54.Riding from this cam portion 176 into cam portion 177 then effectsdenite opening, but not sufficient to drop the suspended blank. At camsection 176 the blank neck 80 is freed to wobble in seeking its centerin blow mold sections 178, 179 (Fig. 3) as closing thereabout, but issufficiently sustained not to be dropped thereinto until the roller 62rides upon cam portion 177. These movements in the continuous rotationof the carriers are so timed that the blow mold 178, 179, issubstantially closed for sustaining the blank neck at the full releaseoperation of thecam 177.

The region of transfer is desirably in the vicinity of the meshing ofthe gears 27, 28, or about at center line 181 between the columns 3, 4.'Ihe speed of operation and character of ware'makes desirableflexibility in operation for locating the point for loosening the blankby the cam 176 and full release-by the cam 177 toy match the seams ormold marks. This is effected, even during the operation of the machine.Fixed with the cam 176 are ears 182 in which is slidable stemv 183having threaded portion 184. This stem 183 is rotatable in guide ear 185xed with the relatively slidable cam unit 177. Col- .lars 186 at the ear185 are fixed with the stem 183 and transmit longitudinal shiftingA ofthe stem 183 for positive relocationl of the cam 177, as to the line181, for such advanced or retarded performance as may bein keeping withefficient practice in the machine operation.

Upon passing the transfer station, xed cam 1 80 is effective forwide-spread opening of the mold sections 53, 54 permitting more freedomin heat radiation at the high speed of machine performance hereunder.

Spray Besides-the full opening of the neck nish sections 53, 54, and thewide opening of the sections 45, 46, for mesh clearance with the closingand closed blow mold-sections 178. 179, at the region of the line 181,further mold care provision may be had by directing a spray thereinto.When the liquid be oil, it may serve supplementally as a lubricant,especially for elements of the nipple box.

Reservoir 187 (Fig. 34) is provided with valve 188 which may be adjustedfor a slow dripping action into ductA 189. Pressure air line 190 isshown as having valve 191 which may be struck by a moving part of themachine, as pipe 104, to give but a timed snap opening of the valve 191for a gust of air to blow into the pipe 189 (Figs. 1, 34) for vaporizinga jet of the .cooling medium upwardly discharged by jet 192 into theopen blank mold sections and upwardly ltherepast into the nipple boxthereover.

The blow mold carrier yBlow moldr bottom The spider 194, below the pin195 has horizontal pin 197 pivotally mounting depending arm v198 (Figs.31, 32) having offset therefrom socket 199 with which coacts compressionspring 200 for yieldingly thrusting blow mold bottom 201 upwardly. Thearm 198 is operated by yieldable link 202 extending to lever 203 havingfulcrum bearing 204 on the web of the gear 28 adjacent opening 205therein through which this lever 203 extends to have its roller 206 rideon fixed cam 207.

Hinge pin 208 at the connection of the link 202 with the arm 198,pivotally mounts auxiliary arm 209 having terminal nose 210. The cam 207in the approach to the line 181 has acted upon the roller 206 to swingyieldingly the socket 199 upward into position for the blow moldsections to close thereabout. Cam 211 is then acting upon roller 212.Just after the transfer station, and desirably before any blowing hasoccurred, cam 213 (Fig. 25) acts upon the roller 212 to lmove slide 214(Fig. 31) outwardly. Adjustable clearance 215 therein permits engagementof the nose 210 (Fig. 32) so that a final thrust is effective .on thearm 209 transmitted by slot connection,216 and stem 217 to lock thebottom 201 in elevated position for positive re' sistance to blowing ofthe blank to nished ware form in the blow mold 178, 179. This movementof the mold bottom 201 upward to the position shown in Fig. 32, thrustssuch bottom 201 up into contact with the warmer run-out portion of theblank bottom, tending-to atten such bottom out around the sheared edge.l

has a reheating influence on such chilled edge and tends to spread loutsuch shear mark.

Upon blowing of the blank to ware form, such shear mark is dissipatedlinto a larger diameter region, and ythere is promoted the tendency tohave such mark disappear altogether.

When the blowing operation is completed, cam 218 i (Fig. 25) retractsthe slide 214, and cam portionv219 from the cam 207 is effective foracting upon the roller 206 for swinging the arm 198 inward and witharticle of finished ware 220 lowered from the open blow mold to tilttherefrom to move down chute 221 (Fig'. 31). Working looseness of theparts is taken up in mold closing at wedge face 199.

outward on guide rods 225. Yieldable connectiony 226 is :transmissionfrom this crosshead 224 to auxiliary crosshead 227-having transverseguide way 228 (Fig. 22) for bar 229. Transverse movement of this bar 229servesas van equalizer or compensator. From the bar 229 adjustable links230 extend to angle levers 231 having fixed fulcra 232. Adjustableyieldable links 233 from the angle levers 231 extend to the blow moldsections 178', 179.

From the cam portion 222, concentric cam 234 (Fig. 3) extends forholding the blow mold sections closed during the blowing operation. Camportion 235 effects blow mold opening prior to the dropping away of thebottom 201 for discharging the finished ware. y

Cam 236 (Figs. 3, 31) acts on roller 237 radially thrusting slide 238connected .by yieldable link 239 to angle lever 240 having fixedhorizontal axis fulcrum 241 on the spider 194. This lever 240 carriesadjustable clamp 242 for mounting Iblow head 243 so that in the throwingof such downward it may be nicely adjusted for 1seatingrelation in topclosing of the blow mold. Concentric'cam portion 244 (Fig. 3) holds thisblow head in such position during the blowing interval, and cam portion245 effects lifting of the blow head before the blow mold opening.

Pressure air for the blowing may be supplied by pipes 246 upwardlythrough the column 4 to ring 247 as yieldably pressed by device248against ring 249 (Figs. 26, 27, 28, 29, 30), 250. Handle 251 (Fig. 3)extending to the ring 249 permits from lines 260 extending t'o Athe ring255,' there communicating by groove 261- -with the ports 256 for thetiming effected by the carrier travel. In these adjustments for the twoblowing operations, one may 'be timed as to the other ffor effectingva'distribution of the molten glass in the ware, -even for compensatingwhen 4too thin at the upper portion for-there making the ware moreheavy, with a reverse procedure when' the upper portions are too heavyand the bottom too thin. Controlled glass distribution is thus possible.and the response to this control has as a factor the elapsedtime fromthe gather up' to this interval for the |blowings. That is this moltencondition of the glass is to an extent controlled by making longer orshorter the time blowing occurs after the. gathering operation. Thiscontrol is in lthe speed of the machine.

As the-"blowing operation is completed, and before mold opening, lairfrom a line 260 at port 262 (Fig.`v 29) may communicate with port 263(Fig. 24) for air blow by line 264 extending to the bearing 241 andthence by line 265 to the blow head 243 (Figs. 31, 33) to be thereeffective above piston 266 in depressing such against the resistance ofspring l267, thereby to have pad "268 lowered upon the article of ware220 at the ring to steady such against sticking or lateral shifting asopening of the molds occur. The article is thus left centered on thebottom 201 for definite tilting off in the ware discharged as completedfrom 'the machine.

Operation 'I'he platform 1 is located in gathering proxirnity to theglass tank 35. The motor 7 is started by throwing in the switch 6. Themeshing gears 27, 28, effect synchronous rotation of the carriers ascontinuously moving the series of blank and blow molds. In the instanceyherein shown, center lines 269, 270 (Fig. 21') for the closed blankmolds and closed blow molds, have a slight degree of overlapping at thecenter line 181 between the columns in the region of transfer.Camportion 271 (Fig. l) has` closed the blank mold after the cooling andlubricating treatment. Dipping of the closed blank mold 45, 46, astraveling through the opening 43, eifects suction gathering. Blade 112is swung up from ahead into shearing and blank bottom closing position,for the blank forming and the plunger 73 is then retracted.I The blankmold sections 45, 46, are opened in the travel toward the transferstation, during which interval the burner 173 may remove shear mark andsoften the blank as may be desirable. The neck ring 83 is lifted beforethe v mold sections 53, 54, open in the vicinity of the line 181, wherethe blow mold sections 178., 179,

are closed thereabout. The blank is nowr carried by the second carrierfor stage blowing operations in completing-ware with the mold sections178, 179, opening to 'leave the ware 220 on the bottom 201. Tiltingdownward of this bottom discharges the completed ware from the machine:Inasmuch as the machine has two endless series of these blank and blowmolds,.the stages of blank and ware production are simultaneouslyprogressing in sequence.

The handle 251 adjusts'the time of initial blow and duration thereof.This application is a continuation in part of .my applications forUnited States Letters Patent Ser. No. 282,088, filed June 1,V 1928,Glassware forming, and Ser. No. 99,479, filed April 3, 1926, Glassgathering and forming machines.

What is claimed and it is desired to s ecure by Letters Patent is:

1. A glassware forming machine comprising a rotar-y carrier, anauxiliary relatively shiftable member mounted on the carrier, a fulcrumfor 'rotary carrier, a mold movable relatively to the carrier, and a camas to which the mold is movable by the carrier for eecting controlmovement of the mold, said cam including a relatively rockableterminally pivoted section having its rocking axis in the generaldirection ofthe cam extent, and control means for shifting said sectionto adjust the horizontal v'plane of the mold.

3. A glassware forming machine comprising a rotary carrier, an openbottom mold mounted on.

the carrier, a closure for said mold bottom, a lcam coacting for holdingthe closure in mold bottom closing position, a throw-out cam' .portionfor shifting the closure tomold bottom opening position, and a mountingfor directing shifting of the throw-out cam portion along the othercamand angularly of the carrier.

4. A glassware forming machine comprising a rotary carrier, multipleelement forming means mounted` by the carrier, said means including aneck` opening former and a second neck former thereabout, withdrawaleifecting means for the opening former comprising an arm extendingtherefrom, a. lcam control therefor, there being toggle linkage means coaoting with said arm for locking the former in operative or withdrawnpositions against movement other than cam controlled, and additionalcontrol means for the second former.
